WebThe root node represents the most recent common ancestor of all of the taxa represented on the tree. Time is also represented, proceeding from the oldest at the bottom to the most recent at the top. What this particular tree tells us is that taxon A and taxon B are more closely related to each other than either taxon is to taxon C. WebRooted phylogenetic trees may be oriented horizontally, as above, or vertically. Here the time axis is implicit, running from left to right. The node at the left end of the tree is the root node, which represents the oldest point on the tree. As we move from the root node, we can identify nodes which are ancestral to their descendent clades.
